I just came back from Barnes and Noble and Real of Racket is now in their
Computer books section.

Please work your way thru HtDP/2e first. Realm assumes people have seen a full
course on programming (2e is almost complete) and have the maturity to work
through some typical first problems. When you're done Realm will be just fine
for you. -- Matthias

Saad, at first I thought the problem was you put a space after the
single-quote mark. I tried what you entered using the Beginning
Student with List Abbreviations language, and it worked, space or no
space:
> '((1 3 5 7 9) (2 4 6 8 0))
(list (list 1 3 5 7 9) (list 2 4 6 8 0))

I have been working with Htdp/2 as an absolute beginner and finding it
difficult have switched to Realm of Racket.
In the first pages it asks one to download Racket which I already have but
in the BSL mode. When using it I type in the following in the interactions
panel as advised by Realm of Rac

guess is a procedure, and not a number.
The error message is telling you that it expects a number and not a procedure
as the argument to sub1.
If you evaluate guess in the REPL, you can see the problem:

Glad to hear DrRacket helped you. Don't hesitate to ask for help, but let me
recommend the Racket user list:
users@racket-lang.org
You can sign up at the Racket lang.org web site and the list members are
helpful and quick to jump in.

If the purpose is to work thru a 'regular starter book', Realm of Racket may
work better than 2e at the moment if someone can help. ROAR basically assumes
someone has programmed a little bit in something, anything.
If the purpose is to launch the person on a career in programming, start with
To the authors:
I have recommended Realm of Racket to a friend who expressed an interest
in programming in conjunction with HtDP. Now, I'm sure the creators
would "strongly encourage" future software engineers to be comfortable
with the material in HtDP, but exactly how difficult is the "inte

No, the students had one semester of teaching languages under their belt when
they started. We first translated their knowledge to Racket and expanded from
there. Plus the designers were fa
I've ordered the book with free ebook.
May I ask if the book is written in Scribble?

Dear list members,
Realm of Racket is finally out. For the first 72 hours, NoStarch.com offers a
40% off coupon plus a free
e-book version if you buy the book from their website. Otherwise the book is
distributed through O'Reilly
and is available at the usual places wherever O'Reilly sell
Love the video! I used to say I wished I could recommend Racket for enterprise
development. But no more. Recent developments, such as the math and db
libraries make it an excellent choice.

Perhaps I missed the news, but is there a publication date for
the book yet? I don't see it on the Web site
The following works:
$ echo '#lang racket "hello world"' > hw.rkt
$ racket hw.rkt
"hello world"
ie. racket is a multi-language language, so you must first tell it in what
language you're writing.
That's of course an overhead compared to mono-language languages ;)

I liked it overall. Racket has advanced so rapidly over the last few
years, it really needs to be re-introduced and hopefully will gain a
footing and some sort of viral growth. Marketing is persistence.

I hate to say it but after an initial laugh, that video strikes me as
mostly just snarky and dishonest. A literal isn't the same thing as I/O,
and brevity doesn't have much to do with why I like Racket. What is the
point? Maybe it would make sense with some context.
Sorry if my reaction bothers an
